Ginger (Zingiber officinale Roscoe) and Lachii (Alpinia allughas Roscoe) are well known and widely used herbs. Ethanol, acetone, methanol and n-hexane extracts of Zingiber officinale Roscoe and Alpinia allughas Roscoe roots were screened for their antioxidant activities in an effort to compare and validate the medicinal potential of their subterranean part. Total phenol (mg gallic acid/g dry matter) and flavonoid contents (catechin equivalents/g dry matter) were estimated by Folin-Ciocalteu and aluminium chloride colorimetric tests respectively. Radical scavenging activity by DPPH methods was expressed as percent inhibition. Total phenolic contents varied from 10 ± 0.12 to 14 ± 0.03 mg gallic acid/g for Z. officinale and 5.46 ± 0.02 to 12.9 ± 0.06 mg gallic acid/g for A. allughas. Total flavonoids were 5.33 ± 0.75 to 8.34 ± 2.1 mg catechin/g for Zingiber officinale and 1.50 ± 0.447 to 9.92 ± 2.5 mg catechin/g for Alpinia allughas in four solvents. Maximum phenolic and flavonoid contents were observed in methanol extracts. The antioxidant activity (percent inhibition) of Zingiber officinale and Alpinia allughas ranged from 26.8 to 68.3 and 14.3 to 58.5 respectively in different solvents. Overall, the findings indicate that the both spices are good sources of phytochemicals which could be exploited as great potentials for drugs and/or nutritional supplements. Bangladesh J. Sci. Ind.

The functionality of nutraceutical foods is attributed to their bioactive compounds. These compounds are widely produced by plants, such as phenolic compounds, which have antioxidant activity and/or antimicrobial activity, acting against damage to macromolecules such as lipids, proteins, and nucleic acids. Secondary plant metabolites, including classes such as phenolic compounds, alkaloids, and terpenoids, have a wide variety of biological activities with medicinal potential. These secondary metabolites are considered bioactive compounds. The Zingiberaceae family received special attention for their large bioactive compound production. Such compounds are useful in foods as herbs, spices, flavorings, and seasonings and in the pharmaceutical and cosmetic industries as antioxidants and antimicrobials. Gingers are recognized as safe by the American Food and Drug Administration (FDA), resulting in no side effects when consumed in moderate amounts. Recent studies show that, in addition to rhizomes, the leaves and flowers of some ginger species have antioxidant activity and consequent medicinal potential. Studies have demonstrated that in vitro and in vivo research is needed to evaluate the efficacy of ginger extracts and understand their role in the modulation of biological and molecular pathways, thus enabling the development of new therapeutic strategies. Thereby, the present work aims to provide a bibliographic review on the antimicrobial activity of Zingiber officinale Roscoe and Alpinia purpurata (Vieill.) K. Schum. (Zingiberaceae), popularly known as ginger and red ginger respectively, and their potential use in the One Health initiative.

Since synthetic chemotherapeutic drugs produce a certain degree of drug resistance and due to their common side effects, such as damage to hematopoietic cells and hair loss, it is necessary to use herbal medicine as a substrate to develop new anticancer drugs. The ingredients of three essential oils (EO) were identified using gas chromatography–mass spectrometry (GC-MS) analysis. Their anticancer activities have been investigated on four human breast cancer cell lines, including MCF-7, MDA-MB-175, MDA-MB-231, and MDA-MB-468. In addition, their antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The three plants were investigated for identifications of the ingredients of their EOs, and major ingredients were identified in each plant as alpha-phellandrene (26.75 %) in Anethum graveolens L., limonene (61.83 %) in Citrus limon (L.) Osbeck, and zingiberene (30.28 %) in Zingiber officinale Roscoe. Among the EOs, C. limon was significantly more effective than others; its half-maximal inhibitory concentration (IC50) on MCF-7 was obtained at 201 µg.mL-1. Furthermore, Z. officinale EO showed a higher antioxidant activities in comparison to the two other EOs. Considering the antioxidant and anticancer effects of the EOs, they could be further investigated as a possible complementary medicine in cancer.

The Stability

Carbon dioxide-enriched atmospheres are used to reduce decay incidence and severity and extend the postharvest life of strawberries. However, depending on the cultivar, carbon dioxide concentrations of ≥20% can be detrimental to color (change from red to purple) and flavor (development of off-flavors). Our objective was to determine the effect of elevated carbon dioxide levels on the stability of the anthocyanins and other phenolic compounds to examine their role in color changes of strawberries. Freshly harvested strawberries were placed in jars ventilated continuously with air or air enriched with 10%, 20% or 40% carbon dioxide at 5°C for 10 days. Anthocyanins and other phenolics were extracted at 0, 5, and 10 days from homogenized samples. The samples were purified using Sep-pac C18 cartridges. The purified methanolic extract was injected directly into HPLC coupled to a photodiode array detector. Cyanidin-3-glucoside, pelargonidin-3-glucoside, and pelargonidin-3-rutinoside were identified as the major anthocyanins. After 5 and 10 days in storage there was a reduction in the total amount of anthocyanins. This degradation was lower in air than in carbon dioxide-treated strawberries, but the anthocyanin profile remained the same. Flavonols (e.g., quercetin and kaempferol derivatives) and phenolic acids (e.g., ellagic acid) decreased during storage, and this decrease was exacerbated by elevated carbon dioxide atmospheres. Carbon dioxide-induced changes in the quantities of the previously listed anthocyanins and phenolic compounds may be the cause of color changes from red to purple in strawberries.
